centos7 中安装 mysql5.6 的过程

前提是Centos的环境是好的，并且相关的软件包已经安装好。

1、创建用户，并修改创建的数据目录的属主

[root@bogon ~]# useradd -M mysql -s /sbin/nologin
[root@bogon ~]# mkdir /data
[root@bogon ~]# chown  -R  mysql:mysql /data/

2、安装需要的依赖软件

[root@bogon ~]# yum -y install gcc gcc-c++ cmake ncurses-devel perl-Data-dumper openssl-devel

3、上传源码包，并解压安装

[root@bogon ~]# tar -xf mysql-5.6..tar.gz -C /usr/local/src/

[root@bogon ~]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data \
-DWITH_MYISAM_STORAGE_ENGINE=\
-DWITH_INNOBASE_STORAGE_ENGINE=\
-DWITH_ARCHIVE_STORAGE_ENGINE=\
-DWITH_BLACKHOLE_STORAGE_ENGINE=\
-DWITH_MEMORY_STORAGE_ENGINE= \
-DWITH_READLINE= \
-DENABLED_LOCAL_INFILE=\
-DDEFAULT_CHARSET=utf8\
-DDEFAULT_COLLATION=utf8_general_ci\
-DEXTRA_CHARSETS=all\
-DMYSQL_TCP_PORT=\
-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock\
-DWITH_DEBUG= \
-DWITH_SSL=system

[root@bogon ~]# make && make install

4、进行简单的配置文件的配置

[root@bogon etc]# rm -rf my.cnf.d/
[root@bogon support-files]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

5、进行安装初始化

[root@bogon scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/

执行结果：

-- ::  [Note] InnoDB: Shutdown completed; log sequence number
OK

Filling help tables...-- ::  [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
-- ::  [Note] Ignoring --secure-file-priv value as server is running with --bootstrap.
-- ::  [Note] /usr/local/mysql//bin/mysqld (mysqld 5.6.37) starting as process 37140 ...
-- ::  [Note] InnoDB: Using atomics to ref count buffer pool pages
-- ::  [Note] InnoDB: The InnoDB memory heap is disabled
-- ::  [Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins
-- ::  [Note] InnoDB: Memory barrier is not used
-- ::  [Note] InnoDB: Compressed tables use zlib 1.2.
-- ::  [Note] InnoDB: Using CPU crc32 instructions

-- ::  [Note] InnoDB: Completed initialization of buffer pool
-- ::  [Note] InnoDB: Highest supported file format is Barracuda.
-- ::  [Note] InnoDB:  rollback segment(s) are active.
-- ::  [Note] InnoDB: Waiting for purge to start
-- ::  [Note] InnoDB: 5.6. started; log sequence number
-- ::  [Note] RSA private key file not found: /data//private_key.pem. Some authentication plugins will not work.
-- ::  [Note] RSA public key file not found: /data//public_key.pem. Some authentication plugins will not work.
-- ::  [Note] Binlog end
-- ::  [Note] InnoDB: FTS optimize thread exiting.
-- ::  [Note] InnoDB: Starting shutdown...
-- ::  [Note] InnoDB: Shutdown completed; log sequence number
OK
其中出现两个ok是成功的。

6、启动mysql，并把相关命令添加到环境变量中

初始化之后的说明：
New default config file was created as /usr/local/mysql//my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

配置文件的问题。
[root@bogon scripts]# mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &
[root@bogon scripts]# ps -aux | grep -v grep | grep mysql
root        0.0  0.1    pts/    S    :   : /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf
mysql       0.7 44.8   pts/  Sl   :   : /usr/local/mysql/bin/mysqld --defaults-file=/usr/local/mysql/my.cnf --basedir=/usr/local/mysql --datadir=/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=bogon.err --pid-file=bogon.pid

7、进行简单的mysql的用户的密码修改。

[root@bogon bin]# mysql -u root
mysql> use mysql;
mysql> update user set password=PASSWORD("") where User='root';
mysql> flush privileges;

8、停止mysql的服务

[root@bogon bin]# mysqladmin -uroot -p shutdown

9、错误

编译错误删除

[root@bogon mysql-5.6.]# rm -rf CMakeCache.txt
